hello all,
can anyone tell me the list of methods to override in order to create a
custom TreeModel?
I currently have these:
virtual Gtk::TreeModelFlags get_flags_vfunc() const;
virtual int get_n_columns_vfunc() const;
virtual GType get_column_type_vfunc(int index) const;
virtual void
well, I was trying to come up with a good demo, because I have always
felt that people will like to fill a treeview directly from their own
data
it has been a while since I have worked woth gtkmm, so I adapted the
following from a working program against gtk-2:
the Gtk::Window* do_treeview_memor
indeed! that seems to get me on my way! thanks!
if/when I get this working: would you be interested in adding this to
the gtkmm demo programs?
regards, D.

Have you declared your custom TreeModel something like

Your custom TreeModel can perhaps be added either to the gtkmm
demo programs or to the gtkmm tutorial at
https://gitlab.gnome.org/GNOME/gtkmm-documentation. Let's decide
when you have a working program.
Have you noticed that there is a cust
gui in a separate structure.
Copying the data into the treeview model, as the existing demo programs
do, is obviously not the ideal solution.
the other example in gtkmm-documentation keeps is very helpful, but it
does not show subdirs...
regards, Danny.

Hello all
a question about gstreamermm: I am trying to convert an old project of
mine to the current version of gtkmm and gstreamermm. And there is one
particular problem that I can not solve.
I have a piece of code that extracts a thumbnail picture from a video,
in order to give an idea of what t
I guess the key would be to find the equivalent of the following old
(Playbin2) code
Glib::RefPtr image_buf;(const guint8*)
image_buf→get_data(),
a Buffer is replaced I think by a Sample; but from the documentation I
can not understand how to get at its raw data, and then convert it
to(const guint8
